For reasons of speed and site name control, I have reluctantly moved my site content from a free web hosting service to a paid one. But I want people who find a link to or use a bookmarked to my old site, to see the new one instead.

To avoid violating the terms of this forum, by advertising my site name, I have replaced the free hosting service's server with "imaginarysite1.com", and my registered hostname with "imaginarysite2.com".

The old (free) hosting service, which actually used my files on my google drive, somehow caused my pages in the address line of browsers, on bookmarks, and in search engines, to appear to be on "imaginarysite1.com/imaginarysite2.com".

I use a popular paid name registrar (which also happens to run the new hosting service - but they would allow me to change hosting services again if I so desired), because I have twice lost website names, when prior free hosting services closed down. I have already made sure that my registered website name, "imaginarysite2.com", maps directly to the new hosting address, instead of being somehow redirected to "imaginarysite1.com/imaginarysite2.com". Thus, if they use my registered site name, they get to my new pages.

I also replaced all the HTML files in the google drive, which the old hosting service used, to redirect using thR meta tag "Refresh", to the equivalent pages on my new host. E.g., here is "index.html" on the google drive, which the old service uses:

This works right as far as I can tell, on my PC and phone - though I admit I have reconfigured my browsers in a non-default way.

I try my best to insure that my pages will work correctly with any version of any browser, on any device, and not be blocked by anyone.

Some people say redirects are "dangerous". Is there any chance my old or new page could be labelled "dangerous", by securely configured browsers, search engines, or restricted web services (like child-safe services), causing it to be blocked?

Is there any configuration of any browser on which neither the redirection, nor the alternative link, will work?
